General Purpose
Nontoxic
High Quality Heat Transfer Fluid
AN ECONOMICAL GENERAL
PURPOSE FLUID FOR OPEN AND CLOSED LOOP LIQUID PHASE HEATING
SYSTEMS.
MultiTherm
IG-2 ®
is
a Nontoxic High Quality Heat Transfer Fluid for use in closed
loop, liquid phase heating systems up to 600°F and in open
systems up to 400°F.
MultiTherm IG-2 ® has
been successfully used in a variety of chemical process industry,
it is used in central hot oil systems for heating all types of
process equipment. In asphalt storage facilities, the fluid
is used for line tracing and tank heating. In industries laundries
MultiTherm IG-2 ® provides
higher throughput with a great degree of safety in flat work ironies.
DURABLE
Open Systems
Oxidation and fluid boil-off are major problems when using
organic heat transfer fluids in hot open systems. Oxidation produces
organic acids, which react and create deposits. The rate of boil-off
an oxidation are dependent of the fluid vapor pressure. The higher
the vapor pressure, the greater rate of oxidation and fluid boil-off.
MultiTherm IG-2 ® has
exceptionally low vapor pressure, and as a result its service
life is significantly longer under these severe conditions.
Closed Loop Systems
Closed loop, liquid phase heat transfer systems often operate
for extended periods of time with little or no problems. However,
equipment malfunctions such as circulating pump failures, bypass
valve malfunctions, and cracked heater tubes do occur and can
put extra stress on the heat transfer fluid. If the fluid has
been in service for a period of time, and especially if it has
been exposed to air at high temperature, these malfunctions can
cause rapid degradation and require immediate replacement to prevent
further equipment problems. MultiTherm
IG-2 ® is a highly refined product with proven
resistance to oxidation and thermal breakdown. It can take the
stress without requiring premature replacement.
HIGH FLASH POINT
In certain applications, local, state or federal regulations
may require that the thermal fluid system operate below the fluid
flash point. This can result in the need for greater heat transfer
surface area (more expensive equipment) to achieve required heat
loads. MultiTherm IG-2 ®
has one of the highest flash points of any heat transfer
fluid (440°F / 227°C) which provides maximum system efficiency
under these conditions.
LOWER COSTS
Reduced Equipment Costs
Incorporating MultiTherm IG-2
® in a system during the design phase can reduce
equipment costs. Its extremely low vapor pressure eliminates the
need for pressurized expansion tanks to prevent pump cavitation
and can allow specification of less expensive, low pressure piping
and process equipment. VOC emissions are not normally a problem
with MultiTherm IG-2 ®
since system pressures are low and fluid vapor pressure
is not significant.
Reduced Maintenance Costs
MultiTherm IG-2
® is based on a parrafinic oil that coats all
system surfaces with a protective fluid film. This film provides
outstanding lubricity for moving parts and also helps protect
components from corrosion.
